ThePCB process edgeirefu refu isina bhodhi mupendero wakagadzirirwa nzvimbo yekufambisa track uye kuiswa kwekuisa Mako mapoinzi panguva yeSMT kugadzirisa.Iyo yakafara yemupendero wekuita kazhinji inenge 5-8mm.

MuPCB dhizaini dhizaini, nekuda kwezvimwe zvikonzero, kureba pakati pemupendero wechikamu uye kureba kwePCB kuri pasi pe5mm.Kuti uve nechokwadi chekushanda uye kunaka kwePCB musangano maitiro, mugadziri anofanirwa kuwedzera mupendero wekuita kune inoenderana kureba kwePCB.

PCB maitiro ekupedzisira kufunga:

1. SMD kana michina-yakaiswa michina haigoni kurongeka mudivi rekugadzira, uye masangano eSMD kana michina-yakaiswa michina haigoni kupinda mudivi rekugadzira uye nzvimbo yayo yepamusoro.

2. Chimiro chezvikamu zvakaiswa nemaoko hazvigoni kuwira munzvimbo mukati me 3mm kureba pamusoro pepamusoro nepamusoro pemicheto yemaitiro, uye haigoni kuwira munzvimbo mukati me 2mm kureba pamusoro pekuruboshwe uye kurudyi nzira.

3. Iyo conductive mhangura foil mumupendero wekuita inofanira kunge yakafara sezvinobvira.Mitsetse isingasviki 0.4mm inoda kusimbiswa kwekudzivirira uye kurapa-kusagadzikana kweabrasion, uye mutsetse uri pamucheto mukuru hausi pasi pe0.8mm.

4. Mupendero wekuita uye PCB inogona kubatanidzwa nemakomba echitambi kana V-shaped grooves.Kazhinji, V-shaped grooves anoshandiswa.

5. Panofanira kunge pasina mapedhi uye kuburikidza nemakomba pamucheto wekuita.

6. Bhodhi rimwe chete rine nzvimbo yakakura kupfuura 80 mm² rinoda kuti PCB pachayo ive nepeya yemapendero epacheto, uye hapana zvinhu zvemuviri zvinopinda kumusoro nepasi nzvimbo dzepamucheto.

7. Upamhi hwemupendero wekugadzirisa hunogona kuwedzerwa zvakakodzera maererano nemamiriro chaiwo.
